It's hard to say without seeing the logcat, but surely you are missing to call the commit() method on the FragmentTransaction. Also remember to set the arguments to the fragment before calling ft.commit().

@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
    mFragment = (LayoutFragment) getSupportFragmentManager().findFragmentByTag(mTag);

    if (mFragment == null) {
        Bundle bundle = new Bundle();
        bundle.putInt("noTiles", 4);
        mFragment = (LayoutFragment) LayoutFragment.newInstance(mLayoutId);
        mFragment.setArguments(bundle);
        //ft.add(R.id.content, mFragment, mTag).commit();
        ft.add(R.id.content, mFragment, mTag);

    } else {
        ft.attach(mFragment);
    }

    mSelectedLayoutId = mFragment.getLayoutId();
}

To pass argument to your fragment, it's recommended to create a public static method to instanciate your fragment like :

public static MyFragment newInstance(String firstArg) {
        MyFragment f = new MyFragment ();
        Bundle args = new Bundle();
        args.putString("ARG1", firstArg);
        f.setArguments(args);
        return f;
    }

And then retrieve your args in onCreateView() method like :

String arg = getArguments().getString("ARG1");

Use the static method to instanciate a new fragment with your arguments in other fragment or activities like :

MyFragment f = MyFragment.newInstance(myArg);

In your activity

Bundle args = new Bundle();
args.putString("Menu", "Your String");
Fragment detail = new FragmeantOne();
detail.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, detail).commit();

In your Fragment.. in onCreateView()

String menu = getArguments().getString("Menu");
someTextView.setText(menu);

You can use Bundle to transfer data from activity to fragments or transfre data from fragment to fragment.

Bundle bundle = new Bundle();
DisplayDataList fragment = new DisplayDataList();
bundle.putString("listitem", "Buyer,Seller");
            fragment.setArguments(bundle);

            getFragmentManager().beginTransaction().replace(
                    R.id.frame_container, fragment).addToBackStack(null).commit();

Where you want to recieve that bundle i.w in DisplayDataList Fragment class. You have to use getArguments() method.

DisplayDataList

 Bundle bundle = getArguments();
            String getdata = bundle.getString("listitem");
            System.out.println("Data got-->>> " + getdata);

Hope this will help you.
